The Pentagon has withheld payments of $7 million a piece on the first four F-35s upgraded by Lockheed Martin Corp., with the fighter jets placed in storage until testing shows its software delivers on new capabilities.

Lockheed is on contract to deliver an additional nine TR-3 jets a month with improved software and hardware, or as many as 45 more, by Dec. 31.
